In this PR, the following changes were made:
1. Replaced `raise newException(OSError, osErrorMsg(errno))` in batches
with `raiseOSError(errcode)`.
2. Replaced `newException(OSError, osErrorMsg(errno))` in batches with
`newOSError(errcode)`.
There are still some places that have not been replaced. After checking,
they are not system errors in the traditional sense.
```nim
proc dlclose(lib: LibHandle) =
raise newException(OSError, "dlclose not implemented on Nintendo Switch!")
```
```nim
if not fileExists(result) and not dirExists(result):
# consider using: `raiseOSError(osLastError(), result)`
raise newException(OSError, "file '" & result & "' does not exist")
```
```nim
proc paramStr*(i: int): string =
raise newException(OSError, "paramStr is not implemented on Genode")
```

Per manual, `panics:on` affects _only_ `Defect`:s - thus `sysFatal`
should not redirect any other exceptions.
Also, when `sysFatal` is used in `nimPanics` mode, it should use regular
exception handling pipeline to ensure exception hooks are called
consistently for all raised defects.

…eDefault` warnings
avoid issues mentioned by https://forum.nim-lang.org namely, it
allocated unnecessary stack objects in the loop
```c
while (1)
{
tyObject_N__8DSNqSGSHBKOhI8CqSgAow T5_;
nimZeroMem((void *)(&T5_), sizeof(tyObject_N__8DSNqSGSHBKOhI8CqSgAow));
eqsink___test4954_u450((&(*t_p0).data.p->data[i].Field1), T5_);
}
```
It might be more efficient in some cases

`{.push overflowChecks: off.}` works in backends. Though it could be
implemented as a magic function.
By inspecting the generated C code, the overflow check is eliminated in
the debug or release mode.
Likewise, the index checking is probably not needed.

The documentation links for `parentDir()` and `getCurrentDir()` are
broken as they are no longer part of `std/os`. Link changed to
`std/private/ospaths2`.

1. `freeAddrInfo` is called prematurely, the variable `myAddr` is still
in use
2. Use defer syntax to ensure that `freeAddrInfo` is also called on
exceptions

Edit: also fixes `result.addrList` when IPv6, which previously only
performed a `result.addrList = cstringArrayToSeq(s.h_addr_list)` which
does not provide the textual representation of an IPv6
